Question

According to the law of gravitation each and every object have a force of attraction given by the formula F=Gm1m2÷d^2 but if the distance between 2 object is infinite then the force will be zero. prove this​

Answer 1

Answer:

because the air will not carry both object

An object is falling on the top that is only free fall

Answer 2

Answer:

$\huge\underbrace\mathcal{AnsWER}$

The combined mass of the rider and the bike = 63 kg

Initial Velocity = 8.5 m/s

Final Velocity = 0 m/s

The time in which the bike stops = 3 s

The net force acting on the body is equal to the rate of change of momentum of the object.

F = ∆P/∆T

The momentum of a body with mass m and velocity v is given by p = mv

Hence, the change in momentum of the car is given by ∆P = MV - MU = M ( V - U )

Hence, the net force acting on the car is given by F = M ( V-U) / ∆T

Substituting the value, we get

F = 1.8 × 10²N
